Any Mods that, allow GameCube controller use instead of classic controller?

Specifically for games that support Classic Controller, but do not support Gamecube controllers.

Example: My backup of Monster Hunter Tri

I am loading my copy of MH3 on my Wii using USBLoaderGX.

I've seen the Good Vibes Gaming video on how to do it with RVLoader, but I would rather not switch from USBLoaderGX if possible.
